- Optimized configuration with weight and KV cache quantization (w8a8kv8)

# Key Features
- Model Architecture: Based on the Llama architecture with 70B parameters
- Optimized Performance: Achieves 1.6× higher throughput with w8a8kv8 configuration
- Quantization Innovation: 
  - Weight quantization
  - KV cache optimization using fp8
- Context Length: Supports up to 131,072 tokens
- Precision Options: 
  - bf16 for standard version
  - w8a8kv8 for optimized version

# Methods
The model employs advanced quantization techniques:
- Weight quantization for model compression
- KV cache optimization using fp8
- Backend optimization with FLASHINFER for enhanced performance

# Model Usage

## Quick Start

For optimal performance with w8a8kv8 configuration:
```python
# Environment setup
export VLLM_ATTENTION_BACKEND=FLASHINFER

# Model configuration
